Rationalizing the denominator with two radicals in the denominator

The video tutorial explains how to simplify radical expressions by rationalizing the denominator. It begins with an introduction to the concept of using conjugates for rationalization. The tutorial then demonstrates the application of the distributive property and the product of radicals in simplifying expressions. It further explains the process of simplifying the denominator using the difference of squares. Finally, the video concludes with the final simplification and presentation of the answer.

Describe the difference of two squares and how it is used in simplifying the denominator.

How do you combine like terms when simplifying the final expression?
